Title: | Chilean needle grass ('Nassella neesiana') - integrated grazing for success | Contributor(s): | Grech, Charles J (author); McLaren, David (author); Chapman, David (author); Sindel, Brian Mark (author) | Publication Date: | 2005 | Handle Link: | https://hdl.handle.net/1959.11/10853 | Abstract: | Concern about the invasion of pastures in southeastern Australia by Chilean needle grass ('Nassella neesiana'; CNG) began to mount in the 1970s. Native to temperate South America, CNG can completely over-run pastures resulting in canopy cover of up to 60%. Such infestations lead to a substantial reduction of stock carrying capacity during late spring and summer when the weed produces large quantities of unpalatable flower stalks. By the 1990s many farmers in New South Wales and Victoria found that they had expanding cover of CNG in their paddocks. Moreover, the weed has been invading conservation areas comprising native grasslands, grassy woodlands and riparian vegetation in many areas. The main problem encountered in the management of pastures dominated by CNG is the production of large numbers of unpalatable flower stalks during summer, which are actively avoided by stock, and have sharp seeds which can penetrate the hides of sheep. As 'N. neesiana' is palatable for much of the year, grazing management of this species has been identified as a potential management tool requiring investigation. The project aims to maximise the feed utilisation of CNG, whilst limiting the production of viable seeds, using a range of cultural techniques and grazing strategies that incorporate different classes of stock. | Publication Type: | Conference Publication | Conference Details: | Tussock Terminators Research Forum, Albury, Australia, 2nd - 3rd November, 2005 | Source of Publication: | Proceedings of the Tussock Terminators Research Forum, p. 11-14 | Publisher: | Department of Agriculture, Fisheries and Forestry | Place of Publication: | Canberra, Australia | Fields of Research (FoR) 2008: | 070603 Horticultural Crop Protection (Pests, Diseases and Weeds) | Socio-Economic Objective (SEO) 2008: | 830406 Sown Pastures (excl.
